Quick answer: At a base camp, an area repeller such as a Thermacell does the heavy lifting, clearing a roughly six-metre bubble of still air so a group can sit out at dusk. Add a picaridin spray for when you leave that bubble, permethrin-treated clothing for hands-off, tick-stopping cover all week, and a mesh head net for the nights the bugs win. Treat citronella candles as ambience, not a plan.
There is a precise moment, maybe twenty minutes after the sun drops, when a calm campsite flips into a feeding ground. You feel the first one on your ankle, then your ear, and soon you are doing the slap-dance. That hour after dusk is exactly when you want to sit out with a drink and the fire, and exactly when the mosquitoes, midges and biting flies are worst. A bite is usually just an itch, but mosquitoes carry real disease in some places, so this is one bit of camp kit not to wing.
The mistake almost everyone makes is treating bugs as a single-product problem, buying one can of spray and expecting it to save the evening. What actually works is a layered defence: a clear zone around the chairs, something on your skin for when you move, treated clothing for hands-off cover, and a barrier for when it all gets ridiculous. Here is how to choose, and the gear worth packing.
Quick Picks
- Best area repeller: Thermacell MR450, for a scent-free bubble around the chairs.
- Best for backpacking: Thermacell Backpacker, which screws onto your stove canister.
- Best skin repellent: a 20% picaridin spray (Ranger Ready or Natrapel).
- Best clothing treatment: Sawyer permethrin, for weeks of hands-off, tick-stopping cover.
- Best barrier: a fine mesh head net, the foolproof backup for the worst nights.
How to Choose Insect Protection
Think in layers rather than looking for one miracle product. The base layer is an area repeller. A device like a Thermacell warms a repellent mat and pushes out a protection zone of roughly six metres, no spray and almost no smell, which is the single best way to keep a group of chairs liveable at dusk. The catches are honest: it wants fuel cartridges and mats, takes ten to fifteen minutes to build the zone, and a decent breeze thins it out. For sitting still at camp it is transformative; on a windy ridgeline, close to useless.
The next layer is a skin repellent for when you leave the zone. Three active ingredients actually earn their keep: DEET (still the strongest, but greasy and happy to melt watch straps and synthetic shirts), picaridin (near-identical performance without wrecking your gear, non-greasy, and my default these days), and oil of lemon eucalyptus (plant-based and fine for shorter windows). Here is the myth worth busting: most “natural” botanical sprays and citronella candles fold in genuinely buggy conditions. Match the concentration to how long you will be out, not to a “stronger is better” instinct, since a higher number mostly buys more hours, not more force.
The last two layers are the set-and-forget ones. Permethrin goes onto clothing, socks, shoes and the tent, never your skin, and once dry it repels and kills mosquitoes and ticks for around six weeks or six washes, which makes it the best tick defence there is. When even that is not enough, a mesh head net over a brimmed hat is the layer that never lets you down. The common error is reaching for more DEET when the answer is a barrier and a breezy pitch away from standing water.

Thermacell MR450
This is the piece that changes the evening. It heats a repellent mat over a small butane cartridge and, within a few minutes, the swarm around the chairs thins out and stops landing. Reckon on a mat lasting about four hours and a fuel cartridge about twelve, so carry spares and give it ten to fifteen minutes to build the zone. Do not buy it as your only defence if you are always on the move or camping somewhere windy, because still air is what makes it work. For a fixed base, it is the first thing I pack. Have a quick look at the current and most recent options on Amazon for the Thermacell MR450.
Thermacell Backpacker
Thermacell built this one for people carrying their kit on their back. Instead of its own fuel it screws straight onto the same gas canister you already carry for the stove, so there is nothing extra to pack, and at around a hundred grams it builds the same protective bubble for a fraction of the bulk of the camp models. It is too slow and heavy to bother with on a fast, keep-moving hike, but for weekend trips where you reach a pitch and find the mosquitoes unbearable, it reclaims the evening. Have a quick look at the current and most recent options on Amazon for the Thermacell Backpacker.
Picaridin Spray (Ranger Ready or Natrapel)
If you buy one thing for your skin, make it a 20% picaridin spray. It matches DEET against mosquitoes and ticks but drops the downsides: it is non-greasy, low in odour, and it will not craze the plastic on your sunglasses or eat the coating off a synthetic shirt the way DEET can. A 20% formula generally gives you several hours per application, so you top up rather than marinate. For anything the repeller cannot reach, this is the easy, gear-safe pick. Have a quick look at the current and most recent options on Amazon for the picaridin insect repellent spray.
Sawyer Permethrin
This is the layer people skip and then wish they had not. You spray it onto clothing, socks, shoes and the tent a day before you leave, hang it to dry, and it bonds to the fabric to repel and kill mosquitoes and ticks for roughly six weeks or six washes. Treat your kit once and you get all-week cover with nothing applied to your skin, and it is the strongest tick defence you can carry. Two rules: apply it outdoors and let it dry fully, and never put it on skin, since it is a fabric treatment only. Pair it with picaridin on the skin left exposed. Have a quick look at the current and most recent options on Amazon for the Sawyer permethrin clothing treatment.
Mesh Head Net
Unglamorous and unbeatable. When the midges come in clouds on a still, damp evening, a fine mesh net slipped over a brimmed hat keeps every biter off your face and neck, using no chemicals and weighing next to nothing. It costs a couple of coins, packs to the size of a golf ball, and lives in a pocket as insurance for when repellents cannot cope, with a full bug jacket for the body when it is truly brutal. Nobody looks good in one, and nobody wearing one cares. Have a quick look at the current and most recent options on Amazon for the mosquito head net.

Frequently Asked Questions
Does a Thermacell actually work or is it hype?
It genuinely works, with one condition: still air. Give it its ten to fifteen minutes and it clears a real zone around the chairs. A steady breeze scatters the vapour, so on a windy pitch you will do better with treated clothing and a net.
Is DEET or picaridin the better choice for camping?
For most trips, picaridin. It performs almost identically against mosquitoes and ticks without the greasy feel or the way DEET melts plastics and synthetic fabric. Keep some high-strength DEET in reserve for the heaviest swarms, but reach for picaridin day to day.
What actually stops ticks rather than just mosquitoes?
Permethrin on your clothing does the real work, backed up by tucking trousers into socks and doing a proper tick check at the end of the day. Skin repellent helps on exposed areas, but treated fabric stops them getting a hold.
Do citronella candles and repellent wristbands work?
Barely, once the bugs are serious. They smell pleasant and add a bit of atmosphere, but they will not hold a zone or protect your skin the way a repeller, a spray or treated clothing will. Enjoy the candle, but do not rely on it.
The Bottom Line
Bug protection is a layered job, not a single purchase. Run an area repeller to keep the chairs liveable, carry a picaridin spray for when you move, treat your clothing with permethrin for hands-off, all-week and tick cover, and keep a head net in the pack for the nights nothing else copes. Add a breezy pitch away from standing water and long, light sleeves at dusk, and you get the evening while the bugs go hungry. Active ingredients, concentrations and product rules vary by area, so check the label and current local advice before you head out.
If you’re camping somewhere bugs are a concern, this is a sensitive topic for some — if biting insects or disease risk is a worry on a specific trip, it’s worth checking current local health advice too.
